APPARATUS FOR MEASURING GIVEN QUANTITIES OF LIQUIDS.

Application filed May 8, 1923, Serial No. 637,601, and in Switzerland February 28, 1923. i

The present invention relates to means for automatically operating an apparatus for measuring given quantities of liquid.

The new apparatus comprises at least one gauged vessel provided with an inlet and outlet valve means controlled by a springwhich tends to restore the valve means always to the discharge position of said means after the inlet position has been established by hand. During the filling of the vessel these means are maintained in the inlet position by a locking member which is unlocked by the pressure of the liquid when the filling of the vessel is completed.

The annexed drawing is a sectional elevation of an example of the objectof the invention.

In the drawing a gauged vessel a provided at its top with an air escape device formed by a plurality of capillary tubes '22, and protected by a cap 7) provided with vent holes 11 and with a drain pipe 1 which is connected to said pipe for draining off any liquid which might have passed through the capillary tubes. Vessel a. is besides provided with a chamber 7) filled with hail shot to any desired extent and shut off from the inside of the vessel by screens and intended as a bulb-compensating device as is well known. To the neck 2 which serves alternately as a discharge and inlet neck of the vessel. is at tached a three-way cock g having a handle g and carrying on a square portion of the plug of said cock a collar f having a slot f and a. shoulder provided with a lateral notch f. In the [ill position one arm of the two-armed lever e. is kept engaged in said notch while the other arm leans against a pusher rigidly connected to diaphragm (Z which is exposed to the pressure of the liquid within the inlet neck at the bottom of the vessel a. Cock 9 is also connected to a torsional spring Z attached to a rotably mounted bushing k which serving as adjusting means of said spring, may be controlled by an outside screw 1'. and a set screw in. Spring I- always tends to reestablish the discharge position of the cock and acts also as a pressure spring in so far as it keeps always the plug of cock 9 within its seat. In order to avoid any loss of liquid by casual leakage through the cook, the jointing surfaces of the same are interrupted by grooves s which communicate through pipes 25 with the supply tank not shown.

The liquid is discharged through a nipple f1, and the feeding oi the vessel is effected through an admission neck which communicates with the box of said cock. A'counter C is in operating connection with lever e. The working of this apparatus is as follows:

In the normal position of the apparatus that is in the position of rest, the three-way cock is in. the discharge position with the admission neck shut and the vessel empty. If some liquid is to be measured the handle g is turned so as to point downwards. Then lever 6 under the effect of a spring 6 snaps into the notched collar f thereby locking the cock. While the vessel is filling the air escapes through the capillary tubes p. The liquid reaches these tubes and gets suddenly stopped thereby. The return swing imparted thereby to the liquid will cause the diaphragm (l to bulge and push lever 6 out of the notch of the collar so as to unlock it, whereupon spring Z will rapidly turn cock g into its discharge position, and the contents of the vessel will be discharged.

Having now fully described my invention what I claim as new and want to secure by Letters Patent is 1. Liquid measuring apparatus which comprises in combination, a gauged vessel having at its bottom a neck for the admission and the discharge of the liquid, and atits top means permitting the escape of air but substantially preventing the escape of liquid, a threeway cock communicating with said neck and provided with a notched collar fast to it. an admission and a delivery neck communicating with said cook. a pressure responsive device depending on the inside pressure of said vessel, a locking member. bearing on said presure responsive device so as to depend on its movements and capable to engage the notch of said collar and a torsional spring attached to the plug of said cock and to a stationary part of the same and adapted to restore the discharge position of said cock after the unlocking of the cock by the movement of the pressure responsive device.

2. Liquid measuring apparatus of the kind described comprising in combination a gauged vessel having at its bottom a neck for the admission and the discharge of the liquid and at its top an air escape device formed of a ,plurality of. capillary tubes, at

protecting cap forithe same onithe outside of saidvessel, vent holes in said cap and a Within the notch of said collar while locking the cock in position to admit fluid to the gauging vessel. I

4. %In ailiquid measuring apparatus of the kind described and in combination a three- Way cock having a box arranged to control the admission and the discharge of the liquid, a torsional spring attached to said cock andtentlingto normally retain the cock in the discharge ,positiomand means for adjusting said torsional spring comprising a bushing lodged rotatably ,in the box-of said cock, a cap closing said .box, an ad uSting screw fast to said bushingancl .held within said cap and 1a set-screw vadapted .to secure the bushing in an adjusted ,position.

Intestimony whereof I hereunto aflix my signature.
